I'm currently in the process of getting kit put together for the crankshaft, roller bearing (this is an upgrade that will be more durable) and connecting rod kit. I will be setting up to do this a couple different ways. You send the crank to me and I'll rebuild or I can sell you the parts. I'm just putting this out there to see if there is any interest. There currently is nobody doing this and I love this bike. I have the 2003 baja If you're interested contact me through here and I will get back to you ASAP.
